6.42.1 ALC Maximum Threshold for Channels A and B

Sets the maximum level, below full scale, at which to limit and attenuate the input signal at the attack rate

(ALCARATEAB—“ALC Attack Rate for Channels A and B” on page 113).

6.42.2 ALC Minimum Threshold for Channels A and B

Sets the minimum level at which to disengage the ALC’s attenuation or amplify the input signal at the re-

lease rate (ALCRRATEAB—“ALC Release Rate for Channels A and B” on page 113) until levels lie be-

tween the ALCMAXAB and ALCMINAB thresholds.

Note: This setting is usually set slightly below the ALCMAXAB threshold.
